The Schedule referred to in these Letters Patent and making part of the same T9 n whom' n may concer. m is a vertical receiver, which forms an elbow with y Be it known that we, ERNST 'FRANK and JOHN lthe cylinder A. B1 ADT, of Baltimore. iut-hcv county of Baltimore a is a funnel, fixed in the top of-'the receiver on, and State of Maryland, have invented a newpand through whichthe material t-o be dried is introduced. improved-Machine for Drying Phosphates; ahd'we o is ashaft, having radial arms, r, and placed crossdo hereby declare the following to he a. full, clear, and wise of the upper part of the receiver m. exact description of the same, reference being had 'The function'of the shaft and arms, whichare made to the accompanying drawing making a partcf this to revolve in any suitable manner, is to distribute the specilication, in which material evenly inthe receiver and cylinder A.
